[reduz]

minizip is needed, but I'm not sure what the original errors mean. My guess is that gentoo does something weird regarding zlib

[JoseJX]

Gentoo sanitizes the zlib headers because of namespace polution:
https://bugs.gentoo.org/show_bug.cgi?id=383179

This patch fixes it for me and should be okay for distros that don't do this:

[Evi1M4chine]

Just as an info: Godot compiles perfectly fine on Gentoo (amd64) nowadays.
I’ve successfully done Linux, Android and Javascript* builds (debug & release).
So I don’t think this bug is needed anymore.

The integrated libraries are not welcome on Gentoo, and would have to be removed in the ebuild [Gentoo install script], for it to have a chance of becoming integrated in to the package repository. (This is already done with Mozilla software, where it can be turned on with USE flags.)

But generally, everything is fine.

• JS is of course still broken, but that’s another story. :)

[akien-mga]

This issue is old, and apparently fixed judging by the last comment, so archiving it.
